Application filed July 21,

To all whom it may co /mam:

Be it known that I, GEORGES ROUDANEZ, a citizen of the United States, residing at ine-ago, in the county oi Cook and State of Illinois. have invented certain new and useful improvements in a lil-adiaisor Cap for Automobiles, of which the following is a specification.

This invention relates to an improved radiator cap for automobiles and more particularly pertains to a cap that has self-c0nlained means adapting it for additional use an illuminating device for the automobile on which it mounted.

The increasing use of mom-meters and other indicating instruments or ornamental attachments mounted on the radiator caps oi automobiles renders it highly desirable some illuminating means lie provided ell? which will enable such indicating instrumenls "so be easily read at night.

The primary object of the invention is to provide a radiator cap having self contained means cha'r adapt it for use as aniilluminatdevice, and which hurls one of its most important advantages in illuminating the motooneter which is often mounted on the radiator cap.

In its preferred form the invention eontcniplaies in association with a radiator cap provided with. means for mounting a moto- Ineter or other indicating device or attachment thereon. means for illuminating preferably embodying a plurality of outwardly extending arms integrally formed with the can. incandescent electric lainps supported liv the free ends of said arms and securely nod ihei'rlo and mnduciors ion the hips ei'rleuding and through l he arms. through the radiator cap. the -conductors alter pass ng: through the radiator cap 0onl'inue hacl; to oohnection wilh a switch which 7 age mounted on some part of the car easily oece sihle to the (ll'lYW.

1 ligghls used in the device are preferably of the small incaiuleswenl lype which line a relatively small amount of elecas compared "with lhe head lighls and may he used vonliniui l or imeriniltenlly, as: he case may; he. and when the car is parked. the head lights may he turned oil and the i'adiutor cap lights turned on to serve as runnin;- side lights or as parking ii; u-rrchjv Him-ling a cousiiiei'ihle saving in hall eries.

These lights serve to clearly ouisline he car so that in passing dark crossings or turning Clark corners the car is clearlvvisilole to vehicles approacliingifroin either side and danger of collision is therein minimized.

The radiator cap, by reason of its prominent position on the front of the automobile, is an ornale accessory thereof and possesses utlhty even where no mote-meter is m'esent. and another object" of the inrentioh is re PIOVKlG a cap for automobile radiators having self contained illuminating means comprising a plurality of vari-colored smell in eandescent lamps which are adapted lo make the said radiator cap a highly useful and ornamental device.

The invention consists in the novel constructions and arrangements lo he hereinafter described and claimed for carrving oul the above stated ohjecls and such olher olnecls :is will appear from llie follow oescriplion oi a ceriain preferred embodin'ient illustrated in the accompanving dra mg, wherein---- Fig. l is an elevational View of the device mounted on a radhr'ir sho=.vin; a motm meter attached thereto;

Fig. 2 is a sectional \lEW oi? i'he device without a? molooneter attached and showing the arrangementlof the lights and wiring: andv Fig. is a *l'lonal View of a rgnem laryporlion of an arm of the cap lhistrating an allernative mounting for a lamp;

Similar charaeters (lesiggnzzl'e lilac parts in all the figures of the drais'ino's.

Relei-ring ;o the drawings. il, will he seen that the device comnrises a radialor cap ll? having a cyiindricai-shapcd hod l1 and a downwardly extending fhreaded member 1:? engaging a neck member 13 moiuiited on a radiator ll.

A plurality of outwardly extending integrally formed arms or branches 1:) are mounted on th (wandrival-shaped l?((l V ll, each of said. a1 candescent lamp la; mounted on its free end and threaded :l .orein to con' 'ael with an insulated c-ontact member l? -lich is ins rled in an "F g: ol the arm 7. The vol:- laci members 1'4 are connect-d lo condncl ma 19 which "re each insulated or sleam and l and are which or branches having an in-- extends hack to a switch mounted on the dash (not shown). 1

The cap is removable with the lights turned on so that the radiator may be illuminated during the process of filling.

A moto-meter 23 is preferably mounted on the top portion of the'cap in an eccentrically. positioned opening 2i so that the rays at light from the lamps i5 strike the motoaneter in a way to clearly illuminate the face thereof.

In case it is desirable to leave oil the motometer 23, the opening :24 can be stopped up by a plug (not shown). In Fig. 3 is shown an alternative embodiment of the device in which a lamp 25 is pushed into-contact and held in place by a bayonet mounting QG. While the device of my invention entails the specific embodiments set forth herein in order toattain the objects outlined hereinbefore, itis understood that various'minor changes may be made within the scope of the invention.

.Thus it will be seen that a radiator cap has been provided for use on automobiles which in addition to its use as a radiator cap serves also as an illuminating device for the mote-meter which may. be mounted thereon andalso as a parking light and still further constitutes an ornate accessory for an automobile.

I claim:

1. A detachable fixture -for automobile radiators comprising a hollow body having a threaded extension for engaging the radiator body, moto-me'ter mounted on the hollow body, branch like supporting arms on the hollow body, electric illuminating de vices carried by said arms and conductors for said illuminating devices extending through the arms.

2. In a cap for automobile radiators, com:

prising a hollow body having an axial ex-' tension for detachable engagement with the radiator body, a laterally extending hollow arm mounted on said hollow body, anelectric lamp supported by the free end of said arm and a conductor for said lamp extendmg through said hollow body and arm.

prising a hollow body having an axial extension for detachable engagement with the radiator body. a nioto-meter mounted on the cap, a plurality of laterally extending hollow arms integrally formed with said hollow body, incandescent electric lamps for illuminating the moto'meter and supported by the free ends of said arms and conductors for said lamps extending through said hollow body and arms.

4. In a cap for automobile radiators, comprising a hollow body having an axial extension for detachable engagement with the radiator body a plurality of laterally ex tending hollow arms integrally fol med with said hollow body, the outer ends of said arms being provided each with a lamp socket, incandescent lamps directly receivable into said sockets, said arms forming one side of the ,circuit and insulated conductors formin the other side of the cir cult and extending through said arms and hollow .body.

5. In a cap for automobile radiators comprising a body having one end adapted for connection to the radiator body and a laterally extending arm having a recess therein, said recess having a wall at one end, con tact making elements arranged in the recess, one extremity of the arm having means whereby a lamp may be associated with the arm and brought into contact with the contact making elements, said wall. preventing the movement of? the Contact making elements in one direction relative to the-arm.

(3. in a cap for automobile radiators adapted to permit the association of a motemeter therewith, said cap comprising a body having one end adapted for connection to,

the radiator body and a laterally extending arm having a recess therein, said recess having' a wall at one end, contact melting elements, arranged in the recess, one extremity of the arm having means whereby a lamp may be associated with the arm and brought into contact with the contact making elements, said Well preventing the movement of the contact making elements in one dis rection relative to the arm. 8.
